A while back I posted that my bike was running on only one cylinder and was getting the check engine. So had it repaired and it ended up being the ECM. At a bit over $800. Was doing great till lately and now the check engine sign is coming on again alot! All I have to do is switch the key off and turn it back on to get rid of it but why does it keep coming back on after a couple months? Any one have had this problem or know why? Thanks for any answers.
